Energy-Saving External Wall Insulation in New House

External Wall Insulation is a system that wraps a solid-wall property in high-performance insulation board finished with a premium decorative render. Polished Venetian installs it for homes across New House, Kent, cutting heat loss and refreshing the exterior in a single project, with the thermal upgrade and a smart new facade delivered together. Our coverage does not stop at New House. We are equally active in the nearby Kent areas of Farleigh and Goodley Stock, and travel between the three regularly.

Every EWI project follows the same disciplined sequence. It starts with an initial consultation and a free site visit to assess the wall type and condition, then moves to surface preparation and fixing the insulation boards, followed by the artisan application of the decorative render finish coat, and rounded off with ongoing support for any aftercare questions. Each stage sets up the next.

EWI is particularly beneficial for older properties with solid walls that lack a cavity for traditional insulation. Where a cavity-wall home can be insulated from within the wall, a solid-wall home cannot, so insulating from the outside is often the most effective option. It upgrades the whole envelope at once without losing any internal floor space.

Polished Venetian is a Dartford-based finishing specialist rated 5.0 on Google, and we bring the same artisan care to the render over your insulation as we do to our decorative interior work.
